실험 절차

6-(5-benzylbenzofuran-2-yl)-1,2,3,4-tetrahydroisoquinoline (67 mg, 0.2 mmol) was dissolved in methanol (2 ml). DIEA (0.35 ml) and acrylic acid tert-butyl ester (51 mg, 0.4 mmol) were added. The mixture was headed to 90° C. for 30 minutes using microwave irradiation. All the solvents was evaporated and the crude product of tert-butyl 3-(6-(5-benzylbenzofuran-2-yl)-3,4-dihydroisoquinolin-2(1H)-yl)propanoate was used in the next step without further purification. MS (ESI) m/z: Calculated: 467.25; Observed: 468.30 (M++1).
